Abstract
The new genus Spinosuncus gen. n. is proposed for three known species, S.contractalis (Warren, 1896), comb. n., S.praepandalis (Snellen, 1890), comb. n., and S.aureolalis (Lederer, 1863), comb. n. and four new species, S.rectacutus sp. n., S.brevacutus sp. n., S.curvisetaceus sp. n., and S.quadracutus sp. n. from the Oriental Region. An identification key is provided for all species. The habiti and genitalia of all species are figured. The monophyly of the genus is well supported by a phylogenetic analysis based on sequence data of the COI, 16S rRNA, and EF-1α genes. The potential sister groups of the new genus, the interspecific relationships and some intraspecific variations within the genus are discussed.
